For years, movie magic has been "tricking" audiences in to believing that some fantastical worlds and stories are real. Most movie goers know that they are being duped. After all, that's the best part of going to the movies. Suspending disbelief and accepting an entire world as truth can be fun... even if it's just for 90 minutes of your life.

Here are some behind-the-scenes photos from some of the most iconic movies over the decades. No matter how much you love these movies (or how many times you've seen them), we bet you've never pictured them like this before.
